Deriving the 12-lead Electrocardiogram
نویسنده
چکیده
This paper proposes a lead method and a processing means for monitoring the 12-lead electrocardiogram (ECG) with four standard leads. Leads I, II of the M-L leads and leads V1, V6 of the chest leads are used to record the ECG signals. The ECG waveforms of leads V2 through V5 are derived from the input signals using the least squares method based on the Frank torso model. This method makes it possible to monitor the 12-lead ECG during ambulatory and long-term bedside monitoring. Examples recorded in the hospital environment show that the derived ECG waveforms can reproduce main features of the original signals, including the ST segment changes. The advantages of this method are discussed with compared to Dower’s EASI ECG.

Deriving the 12-lead Ecg from Easi Electrodes via Nonlinear Regression
The standard 12-lead Electrocardiogram (ECG) is the basic clinical method of heart disease diagnosis. Measuring all 12 leads is often cumbersome and impractical especially on a long term monitoring. In 1988, Gordon Dower has introduced an EASI-lead ECG System, where only 5 electrodes are used. In order to gain all 12-lead ECG back from this EASI system, Dower’s equation was proposed then. Ever ...

متن کاملNovel Method for Deriving Vectorcardiographic Leads Based on Artificial Neural Networks
Many methods for deriving vectorcardiographic (VCG) leads from 12-lead electrocardiogram (ECG) were published. All of them are based on a linear transformation. Differences are only in coefficients of transformation matrixes which are designed based on a model or on linear regression methods. This paper presents and assesses a new nonlinear transformation method based on artificial neural netwo...

The issue of whether a traditional or scientifically based system for applying electrodes to the body for routine electrocardiography may be resolved by deriving the 12-lead ECG from the Frank XYZ signals. The result, the ECGD, is sufficiently close to the ECG for serial comparisons to be valid. Reducing data acquisition to the XYZ signals alone has several technical advantages. These have been...
متن کاملComparison of 12-lead and computer-analysed 3 orthogonal lead electocardiogram in coronary artery disease.
The computer-analysed 3 orthogonal lead system ("3-lead ECG") provides a rapid and consistent interpretation of the electrocardiogram. In 102 patients undergoing selective coronary arteriography, the ability of such a system to predict the presence of absence of coronary artery disease and the site of myocardial ischaemia was compared with that of the conventional scalar electrocardiogram inter...
